Kakashi should be given a new Sharingan. it seems like a waist to allow a shinobi like Kakashi to be nerfed so much. in my opinion for the sake of stability, they should ask some of the shin clones to offer up a sharingan or 2 to kakashi. and since the shin clones have a zero rejection rate, they could transplant kakashi's eyes into one the shin clone who gives up a sharingan. that way the clone isn't blinded
